FOUNTAIN PEN.

Apiiueatim'mcd August-31,1928. serial N0.'3o3,279.

This invention relates to fountain pens and has particular relation tothe prevention of sweating ofthe pen whennot in use. I have observedgthat when fountain pens are capped and not in use7 sweating occurs on the inside of the cap.v After the sweating has taken place andthe `Capris loosened,

the sweat, falls andr cornes into contact with the finger pieceof the pen, thus exposinglthe fii'igers 'of the writer to the probability'of becoming soiled. j n 'n It is the primary objectofiniy invention to provide a ineens for preventing' the tendency for fountain pens to sweat. l Y Another object of rny invention isthe pro;

vision of a means for sealing the space around the pen point and feeding device .of afountainpen. `l Another objectfoffniy invention is the pro` vision of a flexible sealing means around the'.

pen point and feeding device. v l

Another object of iny inventionisthe provision of a soluble sealingineans-,as a soluble rubber7 placed about-the, pen pointA and feeding device of a fountain pen. Y

Similar reference characters refer tothe same or similar parts throughout the seiferal viewsofthe drawing. In attempting tolprevent the well known lsweating of fountein pens, I found that by sealing up the end of the pen aroundthe pen point and feeder piece7 vcould prevent the tendency tosweat by 'preventing the creeping of the inlralong-j the outside of the feeder piece :and pen point.
